Li-Bearings tsa Tšehetso VS Li-Bearings tsa Thrust

 

1. Li-Bearings tsa Tšehetso le Mosebetsi oa Tsona

Li-bearing tsa tšehetsoke karolo ea bohlokoa ea turbine ea mouoane. Bearing e kholo e boetse e bitsoa bearing ea radial.

Mosebetsi oa eona ke ho tšehetsa boima bohle ba rotor le matla a centrifugal a bakoang ke ho se leka-lekane ha boima ba rotor, le ho fumana boemo bo nepahetseng ba radial ba rotor ka har'a silindara. Kaha bearing e 'ngoe le e 'ngoe e tlameha ho mamella meroalo e phahameng 'me shaft journal e potoloha ka lebelo le phahameng, li-bearing tsa turbine ea mouoane li sebelisa li-bearing tse thellang tsa mofuta oa journal tse thehiloeng molao-motheong oa ho tlotsa ka mokelikeli. Filimi ea oli e tlotsang e hatelletsoeng e thehoa pakeng tsa shaft journal le bearing, e hlahisang khohlano ea mokelikeli ho netefatsa ts'ebetso e sireletsehileng le e tsitsitseng ea turbine ea mouoane.

 

Ho na le mefuta e mene e meholo ea li-bearing tse kholo tsa turbine ea mouoane: li-bearing tsa tšehetso ea khetla ea cylindrical, li-bearing tsa tšehetso ea khetla ea elliptical, li-bearing tsa tšehetso ea wedge ea oli e meraro, le li-bearing tsa tšehetso ea pad e sekametseng.

 

2. Mosebetsi oaLi-Bearing tse Otlollang

Mosebetsi oa bearing ea thrust ke ho mamella thrust ea axial ea rotor nakong ea ts'ebetso le ho fumana le ho boloka boemo ba axial ba rotor ea turbine le silindara.

 

Li-bearing tsa Thrust li ka etsoa e le li-unit tse ikemetseng kapa tsa kopanngoa le li-bearing tsa tšehetso ho ba yuniti e le 'ngoe, e bitsoang bearing e kopaneng (e kopantsoeng le ts'ehetso ea thrust).

Ka sebopeho, li ka ba likarolo tse ngata kapa tsa sebopeho sa lekala; hajoale, mofuta o sebelisoang haholo ke bearing e bōpehileng joaloka lekala. Likarolo tsa eona tse ka sehloohong li kenyelletsa li-working pads, li-pad tse sa sebetseng, li-shim tsa tokiso le masale a ho kenya.

 

Mahlakoreng ka bobeli a diski ea ho qhaqha, ho kentsoe li-pad tse leshome ho isa ho tse leshome le metso e 'meli tse sebetsang le tse sa sebetseng. Pad ka 'ngoe e kentsoe lesale la ho kenya; li-pad tse sebetsang li na le thrust ea axial e ka pele ea rotor, 'me li-pad tse sa sebetseng li na le thrust ea axial e ka morao.

 

Di-pad tse sa sebetseng tsa bearing ya ho kganna hangata ha di jare kganna efe kapa efe. Leha ho le jwalo, ha mojaro wa turbine o fokotseha ka tshohanyetso, jwalo ka ha mojaro o hanelwa, turbine e ka nna ya ba le kganna ya axial ka lehlakoreng le fapaneng le phallo ya moya. Nakong ena, di-pad tse sa sebetseng, ka filimi ya tsona ya oli e bōpehileng jwalo ka wedge, di thusa ho leka-lekanya karolo ena ya kganna ya axial, ho thibela ho falla ho feteletseng ha turbine le ho qoba ho thulana le ho senyeha pakeng tsa dikarolo tse tsamayang le tse sa sisinyeheng.

 

3. Liparamente tsa Tlhokomelo ea TSI Nakong ea Ts'ebetso ea Turbine ea Mouoane

1. Thepa ea tšepe e tšehetsang e nang le mocheso o tlase ho 105°C.

2. Mocheso oa tšepe o nang le tšupa-tsela < 100°C.

3. Mocheso oa sefahleho o sebetsang oa li-push pad tse ka tlase ho 100°C.

4. Mocheso o sa sebetseng oa sefahleho oa li-push pad tse ka tlase ho 100°C.

5. Ho falla ha Axial < 1.2 mm le > -0.6 mm.

6. Katoloso e fapaneng ea silindara ea khatello e phahameng le e mahareng < 6 mm le > -3 mm.

7. Ho thothomela ha sekoahelo sa bere < 0.05 mm, ho thothomela ha sistimi ea shaft < 125μm.

8. Ho kheloha ha katoloso e bapang ea lisilindara tse letšehali le tse letona ho lokela ho ba ho honyenyane.
